Frequently Asked Questions

The MF4450 prints, copies, scans and faxes — which jobs draw on this cartridge?

Three of the four. Prints, copies and received faxes all put toner on paper; only scanning leaves the cartridge untouched. For a front-office MF4450 that means the cartridge feeds your own printing plus whatever arrives by fax, and those two streams together — not your print queue alone — decide how long the rated 2,100 pages last. A month heavy on incoming orders and signed forms returned by fax will shorten a cartridge's life in a way the print log never explains.

Faxes keep printing overnight — should I keep a spare specifically for that?

If the fax line matters to the business, yes. The MF4450 holds incoming faxes in memory when it cannot print, which covers a short gap, but a cartridge that dies on Friday evening can leave a weekend of documents waiting until Monday. A $26.19 spare on the shelf removes the risk entirely, and a sealed cartridge stores flat in a drawer or cabinet without any special care — cool, dry and out of direct sunlight is all it asks.

Is this the cartridge the imageCLASS MF4450 takes?

Yes — this listing is the Canon 128 black cartridge for the imageCLASS MF4450, rated at 2,100 pages. The label on the cartridge you lift out will read 128; that is the only check the machine asks of you. Fit the new one, close the cover, and prints, copies and incoming faxes resume with nothing to reconfigure on the machine.

What is the real per-page cost for a machine doing this much mixed work?

At full rated yield, $26.19 over 2,100 pages is about 1.25 cents a page. Two honest footnotes: received faxes and copied forms tend to run a little denser than plain letters, so a mixed-duty machine lands slightly under the rating; and a single cartridge is priced for convenience — the same Canon 128 in multi-packs brings the per-page cost down for offices that already know their volume. For a first restock or a modest line, the single is a fair, predictable buy.

Copies through the document feeder look worse than copies off the glass — cartridge problem?

Almost never. Feeder copies pass the page over a narrow scan strip, and a single speck or streak of grime on that strip prints as a line down every fed page while glass copies stay clean. Lift the feeder, wipe the thin glass strip with a soft cloth, and copy again. When prints, glass copies and feeder copies all share the same fading, then look at the cartridge: rock it gently side to side to redistribute the toner before deciding it is empty.

What happens if this cartridge fails while the fax line depends on it?
